Diethyl Ether → 3-(3-Bromophenyl)butan-2-one

Participants

Reaction Steps

To a solution of 3-bromophenylacetone (4.7 g, 22 mmol) in acetonitrile (100 mL) was added methyl iodide (1.4 mL, 22 mmol) and cesium carbonate (14 g, 44 mmol). After stirring at room temperature for 17 h, the reaction mixture was poured into ether (100 mL) and water (100 mL). The organic layer was separated and the aqueous layer extracted with ether. The combined organic extracts were dried over magnesium sulfate, filtered, and concentrated to dryness to give the title compound.
